How will a mechanic replace my distributor O-ring?
The process for replacing a distributor O-ring is unique to each vehicle. In general, your mechanic will go through the following process to complete your distributor replacement:
- Preparation: Your mechanic will turn off your car and, as a safety measure, they’ll ensure that the battery is disconnected.
- Accessing the distributor: For most vehicles, your mechanic will need to remove your engine’s cover and the air filter housing to access your distributor and the O-ring.
- Marking components: To maintain the exact position of your distributor, your mechanic will mark the location of any accompanying components. This includes the spark plug wires, the distributor cap, the distributor, the distribution drive gear, and the distributors alignment with the engine.
- Removing the spark plug wires: The spark plug wires will be removed from the distributor cap. In some cases, the distributor cap may also be removed. This will give your mechanic access to the distributor.
- Removing the distributor: Your distributor will be held in place by bolts or clamps. Your mechanic will remove these bolts and then carefully take out the distributor from its housing position.
- Removing the old O-ring: Using an O-ring removal tool, your mechanic will separate the old O-ring from the distributor. The O-ring may break during removal, which could leave behind debris on the distributor. The mechanic will remove the debris before installing the new O-ring.
- Installing the new distributor O-ring: Your mechanic may use a light coat of oil to install the new O-ring into the exact position as the old O-ring. This installation is typically done by hand.
- Reinstalling the distributor: With the distribution gear in the correct location, your mechanic will lower the distribution back into its original engine-aligned position.
- Reinstalling the spark plug wires: The spark plug wires will be reinstalled in the correct order, and if it was removed, your distributor cap will also be placed back.
- Reinstalling and reconnecting other components: If your engine cover and air filter housing were removed to access your distributor, they’ll be replaced at this time. Your mechanic will also reconnect your car battery.
- Testing: Finally, your mechanic will check for any oil or coolant leaks around the distributor area. They may also start your car to ensure that there are no unusual sounds or vibrations coming from the engine bay.
What happens if I don’t replace my distributor O-ring?
A bad distributor O-ring can lead to the following issues:
- Oil leaks
- Distributor contamination
- Distributor corrosion
- Electrical issues
- Poor acceleration
- Rough idling
- Decreased fuel efficiency
- Engine damage or failure from oil leaks
What is a distributor O-ring?
A car’s distributor shaft has two seals, one of which is an O-ring.
Your distributor is responsible for sending high-voltage sparks to the correct spark plug wires to help the engine run efficiently. Your distributor O-ring ensures that your distributor is correctly sealed to the engine block, thus aiding the distribution process and the engine’s performance.
When the distributor O-ring in the intake has a leak, oil and grime can form on both the intake and the outside of the distributor. If this happens, the entire distribution process can be disrupted, which will affect your vehicle’s ability to run.
When should I replace the distributor O-ring on my car?
The most common symptoms of a bad distributor O-ring include:
- Oil leaks: Oil leaks around the distributor is one of the main signs of a bad distributor O-ring. If you notice oil leaks under your engine bay, it may be associated with a bad distributor O-ring.
- Engine misfires or rough idling: If your distributor O-ring is damaged, it may leak contaminants into your distributor. A contaminated distributor may cause your engine to misfire when idling, starting, or accelerating.
- Vehicle won’t start: You may have difficulty starting your car if your distributor is contaminated by oil leaks from a broken O-ring.
- Strange smell: If your vehicle smells strongly of burning oil, it could be due to a bad distributor O-ring.
Keep in mind: The symptoms of a damaged distributor O-ring vary depending on your vehicle’s make and model. If you experience any of the symptoms listed above, check your owner’s manual for more information, or talk to a mechanic for professional guidance.
How often should a distributor O-ring be replaced?
Unlike other vehicle parts that require routine maintenance, distributor O-rings do not have official replacement intervals. Unofficially, it’s recommended that you change your distributor O-ring every 100,000 miles.
Some O-rings can last the lifespan of your vehicle, but if you notice signs of damage or oil leaks near your distributor, it’s best to swap out your O-ring. Additionally, if you replace your distributor, it’s a good idea to also replace your distributor O-ring at the same time.
Can I replace my distributor O-ring myself?
Distributor O-ring replacements are fairly straightforward, so you may be able to complete the process on your own.
With that said, your distributor O-ring maintains the sealed connection between your vehicle’s engine block and the distributor. Given that this connection is vital to your vehicle performance, you may be better off taking your car to a professional automotive mechanic for the replacement.
